Sennheiser EW-DX SKM (R1-9) – Digital UHF Handheld TransmitterThe Sennheiser EW-DX SKM (R1-9) digital wireless handheld transmitter is a key component of the Evolution Wireless Digital professional microphone system. Designed for operation in the UHF band 520-607.8 MHz, it ensures stable and clear transmission even in challenging conditions. Thanks to advanced SePAC technology, it offers an input dynamic range of 134 dB, eliminating the need for manual gain adjustment. This solution is ideal for lecturers, presenters, and artists who require reliable equipment with the highest sound quality. The transmitter is designed for seamless integration with management systems such as Control Cockpit and Wireless Systems Manager, making it an excellent choice for complex installations.

Product FeaturesDigital UHF transmission guarantees excellent sound quality without interference or noise. E-Ink display is always on, ensuring that operating parameters are visible even when the battery is removed. Up to 12 hours of operation on two AA batteries or the BA 70 rechargeable battery (sold separately) ensures long sessions without frequent power changes. Charging contacts enable charging in the device using CHG 70N, L 70 USB chargers, or the LM 6070 module (all sold separately). 134 dB input dynamic range eliminates the need for gain adjustment, significantly simplifying configuration. Constant RF power of 10 mW ensures a range of up to 100 meters, performing well even on large stages. Metal housing guarantees durability and resistance to mechanical damage. Standard capsule interface is compatible with a wide range of Sennheiser and Neumann microphone capsules, offering extensive sound-shaping possibilities.

Professional Capabilities for Your CreativityThe EW-DX SKM transmitter is equipped with an intelligent scanning system that automatically finds free channels in the band, significantly speeding up configuration, especially in environments with high frequency density. Thanks to the equal channel spacing technology, the system can efficiently utilize the available spectrum, minimizing the risk of interference. Tools such as Control Cockpit, Wireless Systems Manager, and Smart Assist App enable remote monitoring and management of the entire system, which is invaluable during large productions. The programmable mute switch (AF Mute, RF Mute, or no assigned function) gives the user full control over transmitter operation. Function buttons allow direct setting changes, and the lock function protects against accidental parameter modification. The digital sound trimmer enables precise level adjustment, and the switchable low-cut filter (30, 60, 80, 100, 120 Hz) helps eliminate unwanted low frequencies, such as rumble or noise. The test signal generator facilitates checking the audio path before starting a performance. Moreover, the transmitter supports band switching up to 88 MHz, enabling flexible adaptation to local regulations and working conditions. Thanks to all these features, the transmitter performs well in both simple applications and complex stage systems.
